Mechanical Engineering

The mechanical engineering information implies a branch of physics that studies the way various objects can change their positions. The move is scientifically referred to as a mechanical movement. Isaac Newton was the first the one to come up with this name in his famous writing “Philosophiae Naturalis Principia Mathematica”. The classical mechanics science studies the laws of mechanical movements at slow speeds compared to the speed of light. Albert Einstein generalized this domain by creating the relativist mechanics, able to describe the high speed movements as well. In the end, the last branch of this science – the quantum mechanics – studies the movements of microscopical objects. The mechanical subdomains include statics, kinematics and dynamics. The statics study the conditions used to balance various objects under the action of multiple forces and couples. The kinematics work on the mechanical movements, but neglect the causes. At the same time, the dynamics manages to establish the laws by taking in consideration all the causes that can modify the position of an object.

The mechanical engineering information is provided by a branch of natural sciences that showed up centuries ago. This science played a major role in the development of the human society. Its birth and permanent growth can be seen like a consequence of the practical problems of each age, including constructions, transportation and so on. This field studies one of the multiple characteristics and manifestations of matter – the movement. The movement implies all the changes and processes that take place in the universe, starting with the simple movement and ending with the advanced process of thinking. The matter is inexhaustible, as well as the process to understand it. The classical theoretical mechanics – also referred to as the Newtonian mechanics – studies one of the simplest forms of movement. It is defined as the relative modification of the position of an object or one of its parts related to another object considered to be a bench or to a reference system.

The development of mechanical engineering information in time was done simultaneously with the mathematics. The progresses of one of these sciences trained and stimulated the progresses of the other one. From this point of view, the mechanics represents a model for other basic sciences of nature too, such as physics, biology or chemistry. They used to stick to an analog mathematization process. In order to help with the mechanics development, many of the most important savants of the world joined together and exposed their theories. Their simple renumeration would take too much space. However, some of the essential ones include Aristotle and Archimedes. The first one defined the inaction principle, while the second one is said to be the statics creator. The Renaissance times include a few major names too, such as Leonardo da Vinci, Johannes Kepler or C. R. Huygens. With all these, the major names of the classical mechanics remain Galileo Galilei and Isaac Newton. Galilei established the basic definitions for kinematics, such as the the speed and the acceleration. At the same time, Newton took the mechanics studies to the whole planetary system and defined the first law written as a differential equation.
